Hi. First of all, please check my work history and profile to see my skills on OpenGL ES and 3D and C++ and WebGL.
As you can see, I have strong practical experience on OpenGL ES and shading programming and have built many 3D related apps such as 3D simulation, 3D product configuration and etc, so I can help you build virtual make-up app.
Please discuss more details in chat.
Regards.
